ARTHUR PASS, OF BIRKENIIEAD, ENGLAND.

CAN-OPENER.

SPECIFICATION forming part of Letters Patent No. 617,257, dated January 3, 1899.

Application filed my 8, 1898. Serial No. 685,398. (No model.)

T0 at whom it may concern:

Be it known that I, ARTHUR PASS, a subject of the Queen of Great Britain, residing in Rock Ferry, Birkenhead, in the county of Chester, England, have invented certain new and useful Improvements in Can-Openers, of which the following is a specification.

This invention relates chiefly to can-openers, but is applicable generally to shears for cutting sheet metal or the like.

In the accompanying illustrations, Figure I is a side elevation, and Fig. II is a fragmentary side elevation as viewed from the reverse side. Figs. III and IV are fragmentary sectional views, being taken, respectively, on the lines A A and B B of Fig. 1.

Throughout the drawings the same parts are indicated by the same reference-figures.

l is a flat central or main web, with which the one lever 2 is preferably made integral and to which the other lever 3 is pivoted by the pivot screw or rivet 4E. The projecting part 12 of the web 1 is sharpened, so as to form an incision device. The lower shearing edge 5 is on the side of the projecting piece or blade 6 which is preferably integral with the web 1 and formed by laterally bending the metal of the latter so that its web will be substantially at right angles to the Web 1 and substantiallyparallel to the plane of the material being cut. The lower edge 7 of the blade 8 forms the upper shearing edge and is appropriately beveled to cooperate with the lower shearing edge 5. The blade Sis pivoted by the screw or rivet 9 between the jaws of the forked end of the lever 3, and it is guided by the abutting edge 10 of the web 1, against which it slides.

11 is a projecting tongue formed on the web 1 and bearing against the side of the blade 8 and adapted to keep the latter in close contact with the lower shearing edge 5 and so insure an efficient shearing action. The same result can of course be obtained by rabbeting the edge 10 and the abutting edge of the blade 8.

13 is a spring, such as is usually fitted in appliances of this class to urge the levers 2 and 3 apart.

In opening a can a radial incision is first made in the lid close to the edge thereof by means of the incisiondevicc 12. The part 6 is then inserted and the levers are worked in the usual way, so that the lid is cut out by shearing it around the edge.

It will be observed that from the way in which the lower blade (3 is arranged in the form of a lateral projection it can, unlike the blade of an ordinary pair of shears, be made sufficiently strong with very little projection below the level of the material being cut, and, further, that the levers and the pivot 4 are kept well above the said level and that the upper blade 8 ends at the line 10. These features enable the implement to be used with much facility for curved work, as the blade 6 can be easily slid over the part which has been sheared down by the blade 8,. and it is obviously applicable not merely as a canopener, but for cutting sheet metal or the like generally, and it is especially useful for cutting out holes in such material.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In combination, a main web having a cutting-blade at its lower part, the web of said blade, in rear of its cutting edge, being bent laterally from the main web substantially at right angles to lie substantially parallel to the plane of the material being cut, a cutting-blade extending substantially at right angles to the lower cutting-blade, a lever extending from the main web, and a second lever pivoted to the said web at a point above the plane of the cutting edges, and connected to the second cutting-blade, substantially as described.

2. In combination: a web 1 and a lever rigid therewith; a lower cutting-blade projecting laterally from the web; a second lever pivoted to the web at a point clearof the line of the cutting edges; and an upper cutting-blade pivoted at the end of the latter lever and guided by an edge of the web; substantially as described and illustrated.

3. In combination: a web 1 and a lever rigid therewith; a lower cutting -bladle projecting laterally from the web; a second lever pivoted to the web at a point clear of the line of the cutting edges; and an upper cutting-blade pivoted to the end of the latter le and the blade 8 and pivoted thereto substanto tially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

ARTHUR PASS.
